In the modiiied form of Figure 10, the thimble la is provided with agroove 'as in the case of the other forms, and is provided on each sidewith a perforation 24 of suicient size to allow the rope section Illa topass throughit-Without being caught or cramped. Adjacent its lower end,the

thimble is provided on each side with a projec- .tion,25.about which therope, ends vI Ia and I2a may be wrapped, the rope end being arranged sothat it passes over itself and is gripped as .shown by a J-bolt 26,which is secured by a nut v2l. The projection 25 may be omitted or usedif desired. It is convenient to use it on relatively large sizes of ropeor cable and it is notv necessary on smallerA sizes. On smaller` sizes,the rope ends are merely twisted about the shank On larger sizes whereit is 25 is an added convenience. A

.In the forms shown in Figures 12 and 13, the Vthimble is generallythesame as that shown in Figures 10 and 11, as in that form the thimble isprovided with perforations or passages 24h vthrough which the ropesection Illb may pass and the rope ends IIb and I2b are received ingrooves or depressions 2lb Which may be formed .inthe exterior of thethimble and are held in place therein by U-bolts 28 which areY securedby nuts 29. The grooves 21 may be angularly disposed with respect to thegroove 2 as shown in Figure 13, or they may be otherwise arranged.

,I We claim:

1. In combination in a rope thimble, a member dening an eye and having agrooved exterior, and a rope having apair of rope ends, each beingpassed oncev about said eye and having its free end secured to said eyedefining member `and a pivoted hook pivoted on and depending from said.eye defining member,`said .rope being free at all points away from saidthimble and adapted to engage said hook.

2. In combination in a rope thimble, a member defining an eye and havinga grooved exterior, and a rope having a pair of rope ends, each beinglpassed once about said eye and having its free end secured to said eyedefining member, and being elsewhere in contact with but free to movewith respect to said eye and a pivoted hook pivoted on and dependingfrom said eye defining member, positioned between said rope ends.

3. In combination a sling and thimble, said thimble comprising a memberforming an eye,

`there being a plurality of sockets formed in said eye forming member,said sling having two ends, each end being passed once about said eyeformingmember, once through one of said sockets and into the otherhofsaid sockets, and a Wedge located within each of said sockets and incontact with one of said slingv ends, whereby the sling end is lsecuredin one of said sockets.

4. In combination a sling and thimble, said thimble comprising a memberforming an eye, there being a plurality of symmetrically arrangedsockets formed in said eye forming member, said sling having two ends,each end being passed once about said eye forming member, once throughone of said sockets and into the other of said sockets and being rebentinto said socket, Vand a wedge located within each of said sockets andwithin the bend of said sling endand in contact with one of said slingends, whereby the sling end is secured in. said socket.

5. In combination in a sling, an exteriorly grooved eye-forming member,a rope sling associated therewith, said rope sling having two ends, apair of sockets formed one on each side of said eye-forming member, bothrope ends extending into each socket, one rope end being positionedfreely therein for movement therethrough, the other being reversed uponitself, one reversed portion lying partially within each said socket,and means for securingeach reversed portion Within the socket in whichit lies.

6. In combination in a sling, an eye-forming rope thimble having anexterior groove and a pair of sockets positioned one on each side ofsaid eyeforming member, each socket providing a clearance, a rope endpositioned within said clearance for free movement therethrough, asecond rope end extending into said socket and being bent upon itselfWithin said socket, and means for securing it in position in saidsocket.
